Thank you for this straight-forward, easy to understand tutorial! I have tried setting up many Kubernetes clusters on my own following online documentation and It has never worked correctly for me. Now that I have watched your tutorial, I realize there were so many mis-steps I was making.
I love how you even go over the painful steps that are obvious to intermediate users just looking for a leg up, but not for beginners. Wonderful teaching methods. I absolutely love to see it.
This series is golden. I wish I could contribute more, my budget is too tight this month, but I felt bad watching the series without giving something more than a like back. Fantastic job
At around 46:00, when you are adding the first node to the cluster, I think the reason why it didn't work was because you used the join command for the control-plane instead of the worker node. It didn't appear to be because the time was too long. When you regenerated the join, it provided the correct join for a worker node.
You are absolutely right, it also caught my eye when I viewed the video for a second time and saw that there are two commands for adding nodes to the cluster, one for control-plane nodes and one for worker nodes. The one in this video initially takes the control-plane node command in stead of the worker node command.
THANK YOU! Honestly the best guide on YT. As someone who's versed in Docker i found Kubernetes to require a lot of stuff based on what other UA-camr's were doing and i would constantly be overwhelmed! This was very simple , all requirements were said at the beginning of the video and only those things were used for the video. Simple, to the point and just awesome! Sending much love and many thanks
Jay, thank you so much for this timely tutorial! I have been trying to find a tutorial on how setup Kubernetes in Proxmox for the past couple weeks. And now you released this big guy, which is just as great as the rest of Proxmox related and other videos. Thanks!
Awesome timing! We were just discussing k8s at work last week, and the need to start prep work to set up a development lab at the office to support new projects coming in Jan. Great walkthrough. Noticed a few typo's on the blog (missing the echo "deb..... command, the pod.yml has some extraneous Chapter 18 25, and in service-nodeport.yaml missing the the indent the last line) but easy enough to sort through. Can't wait for more k8s magic! Thanks for all you do!
Nice video for learning Kubernetes, I am thankful I can watch this. I tried to learn it once by myself, long time a ago, but the tutorials back then were so confusing to follow. I am glad to have this and get my foot into Kubernetes. I finally know what it is and why its so popular. I have finish the whole video and proof the setup in the video still valid today. I had trouble with the command to install kubelet kubeadm kubectl, maybe just my mistake, but it was not hard to resolve. The kubelet kubeadm kubectl weren't found in the default ubuntu repo. I managed to follow the official kubernetes guide and used the commands in section "Install using native package management", and successfully install the three packages.
I can always rely on your videos. I never have a tough time following your videos. Super great job always, thank you for all the time and effort you put into teaching. I am new to sys admin and homelabbing and i have learned so much from you. Thank you again
Thanks a lot for this valuable tutorial. However, part of it needs to be fixed or updated as I have faced various errors on the way still this helped me to set up my first Kubernetes cluster!!
Last week I tore down my bare metal kubernetes cluster and installed proxmox on the amd64 nodes. I set up two VMs on each, one for control pane and one for worker. I also wiped the arm64 nodes. I used talos for each VM and amd64 node. It’s quite handy.
Awesome explanations! Do you plan in any time soon to release a video with loadbalancer setup for k8s cluster too ? And maybe a nextcloud server in the k8s cluster? Would be great for sure! 🤝♥️
Thanks a lot for this, Jay. Very helpful. On a side note, I was sitting here getting completely triggered by your pronunciation of sudo and lib. After thinking about it, your way actually seems more correct. My entire Linux career has been a lie 😂
Hey Jay, thanks for the awesome content. However I noticed there is a command missing on your blog post (after curl gpg) for installing the repository.
Great stuff, nice run through getting a cluster up and running. The reason your 1st attempt didn't work was because you copied the "--control-plane" option which means that certificates and keys from the first node have to be copied over before it can also become a controller.
Helped me a lot, minor suggestions: Since the worker node becomes a template, 901 would be a more logical ID. Setting the time zone for the template would have taken care of another tedious to do In the Blog post make sure that copy paste does not inlude additional line breaks. Eventually you may want to fix the sudo typo (instead of suod chown) There seems to be a long command missing in the process of the GPG rings...
Hi Jay, Great walkthrough, thank you. One thing to note is that there's currently an issue when running kubeadm init after installing v1.26 of kubeadm, kubectl and kubelet. For some reason when using that version kubelet fails to start. A workaround is to specify v1.25.5-00 when installing those components via apt.
Step 2 would be to get MetalLB and a PVC provisioner ;) Most would recommend Longhorn but actually I'd like to suggest something else. The Piraeus Operator uses DRBD9 and is much faster, especially on 1Gig connections as reads always happen locally if possible. Longhorn just tanks when having to write a lot and will eventually fall behind in replication. Also don't use the NFS Ganesha server provisioner unless you absolutely have to. It's a chore and highly unmaintained. If you do, be sure to build the image to run it from my MR. That's at least a little more up to date
The step to modify netplan requires nano, which is not part of ubuntu-22.04-minimal-cloudimg-amd64.img (used in the recommended/prior video) 'sudo apt install -y nano' works, just noting it here for folks who might get confused (and for any notes on a future version of this video).
I have a question - what's the advantage of going the route you're describing, as opposed to just installing microk8s from the distribution and calling it a day?
As usual, your videos are fantastic from the fact that you are a great teacher. If I have to be picky, in this video audio is a bit out of sync. ;) . Also, in the blog you forgot to add a command to update k8s packages. Would you consider doing a video on Ansible -AWX at levels 200-300?
DHCP with DynDNS updates make the early parts so much easier. As soon as I give my temlate clone a hostname and boot it, it gets a DNS entry. I still did give them static assignments too.
thanks for the nice tutorial. On the written version, you are missing the step to add the k8s repo, it jumps from adding the gpg key to installing the kubeadm... packages
Awesome. The only comment I have is that you forgat to add the command to link the kubernetes repositories in the blogpost writeup. Other than that, continue the great work!
Hello Jay, what about the database and a second ctrl-node? is there a possibility for a video (for the integraded db shared on different nodes, not with an extra host with my-sql)
Does anyone have experience utilizing Rancher with Proxmox? I have been having difficulties. Would love the centralized manhement of kubernetes that rancher provides.
Have you added Ingress to this setup so that you can access the cluster from outside from your network? Setting this up in AWS is simple you just add LB. What about home network? Have you used Nginx deployed in proxmox as well or maybe metallb?
Hi Jay, this Kubernetes video is straight-forward & to the point. I was wondering if you have pointers on how to perform your steps but using Oracle VirtualBox. If I have 3 Ubuntu 22.04 VMs on VirtualBox with similar specs to your VMs & use /etc/hosts to network them. Is this a good starting point?
Your join command failed at 46:35 because you saved 42:04 the command for joining additional controllers (--control-plane) instead of the worker node join was below (and same command obtain later at 47:04)
Hello sir, really thanks for the video, it's saved my life. I ran it on Ubuntu 24.04 and it works like a charm. But here is my question: I want to add high availability for my cluster with HAProxy. Do I need to use the same command for my other control planes, or do I need another command? thanks a lot have a nice day
Thanks for the video. Love your content. However, the blog post does not match the commands in the video at the point where you need to add the repos for apt. It does not work. Gives me errors that the key is not matching and that the release has no release file. At this point, I am not able to install the kube utils with apt install. Tried using SNAP but that didn't work either. Could you update your blog and video to get us back up to current workings?
... loving this... curious, have you looked at doing this using ansible ? thinking i might want to try that... take the base ubuntu image and do all prep/deployment using a ansible cookbook.
Thanks for a great video!!! I did, however, run into a problem, where I could not create my cluster. As it turns out, the issue lies with an incompatibility between kubernetes version 1.26 and containerd version 1.5.9. The error would look like: "command failed err=failed to run Kubelet: validate service connection : CRI v1 runtime API is not implemented for endpoint...." The fix is quite easy: downgrade to kuberenetes 1.25 (sudo apt remove --purge kubelet && sudo apt install -y kubeadm kubelet=1.25.5-00) or to manually upgrade containerd to 1.6.0 Take a look at question "failed to run Kubelet: validate service connection: CRI v1 runtime API is not implemented for endpoint" on ServerFault.
The issue wasn't that the token expired, but you tried to add the other nodes as control planes. This only works if you copied the right CA certificates first. You should've used the 2nd join command which didn't include the --control-plane argument
When initializing the Kubernetes cluster (40:00), I got an error and I noticed that kubelet was not running. The error was: "command failed" err="failed to run Kubelet: validate service connection: CRI v1 runtime API is not implemented for endpoint \"unix:///var/run/containerd/containerd.sock\": rpc error: code = Unimplemented desc = unknown service runtime.v1.RuntimeService" Installing another version solved the issue: sudo apt remove --purge kubelet sudo apt install -y kubeadm kubelet=1.25.5-00 Another solution would be upgrading containerd to 1.6 or above.
@@cgarafulic just need a "sudo systemctl daemon-reload" then "sudo systemctl enable --now contained" and after that check status "sudo systemctl status contained" , this will help
Jay, thanks for all your videos and your book. I have learnt a lot from you. But one question: Why do you double the amount of work up until the point where you make a template of the worker node? The steps are identical for the worker node and the control node up until that point, so the template can be used to generate all four nodes. I have actually recreated the control node from this template and it works perfectly.
Hello, I would like to have a TrueNas course. I really enjoyed this Proxmox course, especially for its didactic and methodical nature, and the way of explaining and organizing the topics and each of the relevant aspects. While I've heard your recommendations about other channels that deal with TrueNas, they clearly don't deal with it in the same way or as extensively as you do. Thank you very much.
The main issue with covering TrueNAS is that it's BSD and not Linux. But now we have TrueNAS Scale, so there's no reason not to consider covering it. I'll definitely consider that and it does sound like a great idea!
This is a fantastic introduction, but i'm confused as to why you would want multiple k8s nodes on the same vm server? isn't the point fault tolerance and resource distribution? I assumed that it would be best practices to have a single k8s node per physical server, disable HA for those particular VMs (because k8s does HA internally)... keeping HA on for the controller because I don't think the controller is fault tolerant if i'm not mistaken. I admit I'm a total noob with this stuff, but Id like to know more.
As far as I know, distributing the workload on a single physical machine with virtual machines is a valid approach. Like that you have virtual redundancy and scalability. If you want physical redundancy, you could replicate the virtual cluster on a second, third, and so on, physical machine. With this setup, you can distribute the application workload over multiple clusters on physical machines. So if one cluster should fail, you still have additional clusters which will handle the workload of the failed cluster. This multi cluster architecture would also enable running your services on hybrid cloud, multi-cloud, and other infrastructure models.
Can anybody direct me to the latest repository that will be pulling the kubernetes packages from, the command is no longer on the video blog notes and I copied what was shown in the video but I get errors that the repository does not have Release file
Very nice tutorial. I will definitely give it another go after running into some issues in the past. Any idea if the same steps (with some minor changes) work on Debian as well?
Can confirm that it works for the most part. The only real difference is that the version of containerd was slightly different (1.4), so the option for systemd cgroup is slightly different, problem is that there is one that looks like it, but it has to be the one that is in the runc.options section. Thanks again for the awesome video
Hi Jay, thanks for this usefull guide! It's awesome for a noob like me that are learning! Is it possible to manage and view the K8s cluster with an interface like for example OpenLens or something similar? Can it possibly be installed on a dedicated VM or in a Docker container? Thank you!!
Hi There! Love your channel! Any plans to do a Gentoo install. I have been trying to install it on an Asus VivoBook 1TB NVME set up and can’t get it to boot because it gives an error saying it “block device is invalid”.

I have a question - what's the advantage of going the route you're describing, as opposed to just installing microk8s from the distribution and calling it a day?
you get vanilla k8s vs an opinionated/OEM based version of Kubernetes - both have their pros and cons

Hi Jay, I bought your book first edition. Is it possible to update to the newest 22.04 version?
Is it possible to run all config of the nodes and controller usin Ansible or Terraform?
Hi There! Love your channel! Any plans to do a Gentoo install. I have been trying to install it on an Asus VivoBook 1TB NVME set up and can’t get it to boot because it gives an error saying it “block device is invalid”. Makes me think there is a specialized driver that need to be loaded by initramfs before loading the kernel. Very weird… Thanks!
... do you have a video that discusses qemu... why do i need it ?
Very nice. :D Thanks. :D
any chance you do a proxmox with ceph hyper-converged tutorial?
